Atomic oxygen in the atmosphere of Mars has been identified by Scientists for the first time since the last observation 40 years ago. It was spotted using a tool aboard the Stratospheric Observatory for Infrared Astronomy (SOFIA).

  • To carry a 100-inch diameter telescope SOFIA is a Boeing 747SP jetliner adapted.
  • NASA and the German Aerospace Centre are jointly projected it.

Key facts

  • In the higher layers of the Martian atmosphere as the mesosphere the professed atomic oxygen was generate.
  • At Terahertz Frequencies (GREAT) it was recognized by disbursing the German Receiver for Astronomy, a progressive device on one of the observatory’s gadgets.
  • The SOFIA was active to observe only about half the quantity of oxygen expected, which may be due to differences in the Martian atmosphere.
  • In Earth’s atmosphere the explanations were likely due to SOFIA’s airborne location, flying between 37,000 - 45,000 feet, overhead most of the infrared-blocking moisture.


  • Atomic oxygen distresses other airs to discharge from the Mars and as a result an important impact on the planet’s atmosphere.
  • The detection enabled astronomers to distinguish the oxygen in the Martian atmosphere from oxygen in Earth’s atmosphere.
  • Atomic oxygen in the Martian atmosphere is disreputably problematic to degree as far-infrared wavelengths are desired to detect it.
  • However SOFIA help to notice it as it has highly sensitive gadgets counting spectrometer.
  • It should be well-known that the last capacities of atomic oxygen in the Martian atmosphere were complete by the Viking and Mariner missions of NASA in 1970s.
